python-根据关键词匹配连续的内容Ⅱ

运用PyQt5生成可执行小程序：匹配起始关键词到截止关键词区间的pos文件的内容，UTC时间转GPS时间，并清除过程中产生的复制文件。

pos文件如下：

% (x/y/z-ecef=WGS84,Q=1:fix,2:float,3:sbas,4:dgps,5:single,6:ppp,ns=# of satellites
%  GPST              x-ecef(m)      y-ecef(m)      z-ecef(m)   Q  ns   sdx(m)   sdy(m)   sdz(m)  vx(m/s)  vy(m/s)  vz(m/s) age(s)  ratio

2284 109910.000  -2654301.3708   3767745.1125   4394556.4741   5  16   0.0000   0.0000   0.0000   0.0000   0.0000   0.0000   0.00    0.0

小程序界面：

运行pyinstaller -F -w setup.py命令，生成可执行程序：
